Why is PoS not susceptible to selfish-mining attack?

Question

bitcoin

There is a lot of this information about such an attack in the PoW algorithm, but very little for PoS. Maybe someone knows?

Answer 1

miners collude and do what they want?
it works great on PoS cryptocurrencies, why did you decide that?
PoS cryptocurrencies in the vast majority of cases do not protect against blockchain overwriting, do not fall for admonitions. Practice shows that this is exactly the case.
and PoW protects against overwriting not absolutely, but within the cost of this attack, i.e. this consensus guarantees that the attacker will need to spend as much (not less) under such and such conditions (number of confirmations)
ps In addition to the consensus, the blockchain also has a code, an algorithm for the operation of the node.
if the project does not have alternative implementations, there is no strategy for making critical changes to the code base, or these implementations do not imply decentralized decision-making, then no consensus will protect against attackers, because at any time developers can add anything to the code and not even report this 'miners'
